Application April 13, 1956, Serial No. 577,986

4 Claims. (Cl. 216-6) This invention relates to a device for hanging,pasting, and trimming wall paper, and more particularly has reference toa device of this nature which may be summarized briefly as follows:

The device includes a shallow frame of U-shaped cross sectionintermediate opposite ends of which there is provided means forrotatably supporting a roll of wall paper. At one end of the frame,there is provided a receptacle for paste, and rotating in saidreceptacle is a paste applicator in roller form, traversed by the wallpaper as it unrolls. Guide means are provided upon the frame, adapted tolead the wall paper to the opposite end of the frame after paste hasbeen applied thereto, and at said opposite ends of the frame there isprovided roller means adjustable transversely of the frame, and servingthe function of the conventional brush by means of which paper is pastedonto a Wall.

The construction is adapted to permit substitution of a brush for thelast-named roller means, and above the roller means there is provided atrimmer, shiftable transversely of the frame for the purpose of trimmingthe paper at the ceiling and baseboard of a wall. Further, associatedwith one of the guide members of the apparatus is a selvage trimmingblade means, usable either for trimming selvage from the roll oralternateively, for pretrimming a strip of paper to fit in a confinedarea under certain circumstances.

The main object of the present invention is to provide a generallyimproved device of the nature referred to that can be applied withmaximum ease and .facility for the purpose of applying paste to thepaper, applying the paper to a wall or ceiling surface, trimming thepaper at the sides thereof, and trimming the ends of the applied paperat the ceiling and baseboard.

Another object of the invention is to provide means on the devicereadily adjustable for the purpose of accommodating rolls of differentwidths, thus increasing measurably the versatility of the device.

Still another object is to so design the apparatus as to permit itsmanufacture at low cost, while still producing a rugged, eflicientdevice for the purposes stated.

Yet another object is to provide apparatus that will fill the manydesirable aims set forth above, and will at the same time be very light,easy to handle, and usable in almost all situations that may beencountered during the operation of hanging wall paper.

Other objects will appear from the following description, the claimsappended thereto, and from the annexed drawings in which like referencecharacters designate like parts throughout the several views andwherein:

Figure 1 is a side elevational view of a paper hanging, pasting, andtrimming device formed according to the present invention;

Figure 2 is a top plan view in which the paper has been shown in dottedlines;

Figure 3 is a longitudinal section on line 3-3 of Figure 2;

- area to be covered.

Figure 4 is an enlarged transverse sectional view, portions being brokenaway, on line 44 of Figure 3;

Figure 5 is an enlarged, detail sectional view on line 55 of Figure 3;and

Figure 6 is a perspective view of an auxiliary brush that may beemployed according to the desires of the particular user in place of theroller means shown in Figures 1-3.

Referring to the drawings in detail, designated generally by thereference numeral 10 is a rectangular frame, open at top and bottom,said frame including elongated, fiat parallel side frame members 12, 12.The side frame members are disposed in vertical planes, during thenormal usage of the apparatus, and fixedly connected between the forwardends of the side frame members is a cross bar 14 which, as shown inFigure 3, is of substantially triangular section, tapering in adirection forwardly from the frame when viewed in cross section.

In the tapered, forward portion of the cross bar 14 there is formed adovetail groove 16, extending the full length of the cross bar, andopening upon the opposite ends of the cross bar. A roller means isremovably carried by the cross bar 14, and includes a support bar 18,having a dovetail tongue mating with the groove 16 as shown in Figure 3.The support bar 18 extends substantially the full width of the frame,and as will be understood, can be engaged in the dovetail groove byextension through one end of the dovetail groove.

Due to this arrangement, the roller means carried by support bar 18 canbe adjusted bodily in a transverse direction upon the frame, for thepurpose of permitting slippage thereof from side to side so that theroller included in said roller means may be offset to either side of theframe, to permit papering around a window or door frame.

In selected positions to which the cross bar 18 is adjusted transverselyof the frame, it frictionally engages the cross bar so as to be retainedin the desired position.

On opposite ends of the cross bar, there are formed and is appliedsmoothly thereto in the desired area re-' sponsive to movement of theframe the length of the In this connection, the frame can be grasped atopposite sides thereof by the hands of the user. Alternatively, suitablehandle means, not shown, may be incorporated therein according to thedesires of the particular manufacturer. To this end, the frame and allother metal parts of the device, would be light weight metal tofacilitate handling, the convenient and easy handling of the apparatusbeing of course a matter of great importance.

Overlying the applicator means is an end trimming means, includingelongated, straight arms 26 having their inner ends secured'fixedly tothe inner surfaces of the forward end portions of the side frame members12. The arms are extended forwardly above the roller means, incliningupwardly from the frame, and connected between the ends of the arms isaslotted cross member 28 (Figure 3). Slidably engaged in the slot of thecross member 28, which slot extends the full length of the cross memberand has been designated at 3% is a trimming blade 32, having an upwardlyprojecting knob providing a handle. When the paper has been .appliedtothe wall or ceiling, the blade '32 is used to trim the pa-' l Each guideincludes upwardly projecting support arms or standards 34, extendingabove the top edgesof the side frame members 12, and connected betweenthe upper extremities of the support mernbers 34 are closely spaced,straight, small diameter guide bars 36, 38. Mounted upon the upper guidebar 36 are spacer collars 40, 40, these being spaced axially of theguide bar 36 as shown to best advantage in Figure 2. Since the wallpaper W travels through the guides with its pasted side up, the collars40 serve the purpose of preventing dragging of said pasty side againstthe cross bar 36.

Mounted upon the transversely extending guide bar 36 is a selvagetrimming blade including a collar 42 having a set screw for securing thesame in selected positions to which it is axially adjusted along thelength of the guide bar. Fixed to the collar 42 is a depending,triangular blade 44, the cutting edge of which is inclined from thevertical and faced rearwardly as shown in Figure 3, in the directionfrom which the paper is issuing. As the paper travels between theguides, a selvage strip S (Figure 2) may be cut therefrom by the blade44. It will be understood that more than one selvage or trimming blade44 can be provided upon its associated guide, so as to trim selvage fromboth sides of the wall paper if necessary. These trimming blades areadjustable axially of the guide bar 36, independently of one another, so

as to be disposed at selected distances apart, along the length of theguide bar 36.

For the purpose of supporting the roll R upon the frame, there isprovided an elongated shaft 46 having circumferentially grooved endportions 48 engaging in angular slots 49 formed in the respective sideframe members 12.

Mounted upon shaft 46 are spaced, confronting discs or heads 50, 52.Disc 52 is secured to shaft 46 against axial movement therealong at oneend of shaft 46,'so that roll R in every instance will be disposed atone end of the shaft adjacent one side of frame 10. Disc is adjustableaxially of the shaft, into engagament with the opposite end of the roll,so as to permit rolls of different widths to be accommodated in theapparatus.

Mounted upon the rear end of the frame is a means for applying paste tothe unpatterned face of the wall paper W, said means being combined witha rear end guide, about which the wall paper is led prior to passagethereof to the front end of the frame.

- The paste applying and guide means are carried by the frame as a jointassembly capable of being bodily rotated about an axis extendingtransversely of the frame, for a purpose to be made presently apparent.Adjacent each member 12, there is provided a support arm 54, connectedintermediate its ends to a pivot pin 56 (see Figure 4) carried by theadjacent member 12, aspacer sleeve 58 being interposed between said arm54 and members '12. Depending from arms 54 at the lower ends of saidarms is an upwardly opening, trough shaped paste container 60, connectedto arms 54 for pivotal swinging movement about an axis paralleling thatdefined by pins 56. Con-' tainer 60 is so connected to arms 54 by anelongated roller shaft 62, carrying a paste applicator roller thatincludes a hard core 64 about which is circumposed a thick sponge rubbersleeve 66, enclosed within a relatively thin covering 68 of a materialimpervious to the passage of paste therethrough, the covering 68 beingcorrugated from end to end thereof. In a preferred em:- bodiment it isanticipated that the surface of the cover: ing.68 will haveapproximately eight corrugations to the 4 inch, but this number may bevaried according to the desires of the particular manufacturer.

Formed upon the container, along one side thereof (Figure 3) is aninwardly directed longitudinal flange 70 to which is secured aresiliently flexible wiper strip 72 extending into contact with theapplicator roller to wipe excess paste therefrom. I e

In the upper ends of arms 54 there are formed short, closed longitudinalslots 74 receiving the ends of a guide roller shaft 76 carrying a guideroller 78, resiliently biased toward the applicator roller by thecontractile springs 80 connected between spacer sleeves 58 and theends'of shaft 76.

Paper as manufactured is rolled in either of two ways, from the bottomof the pattern to the top or vice versa. The drawing illustrates paperthat unrolls from the bottom of the wall to the top and under thesecircumstances the paste. container, applicator roller, and guide roller78 are positioned as shown. Forpaper that unrolls from the top of thewall to the bottom, the device is bodily inverted. Under thesecircumstances, arms 54 rotate degrees about pins 56. This rotates thecontainer, applicator, and guide roller as a unit until they. are onceagain in the position shown in Figure 1, with the frame being invertedas mentioned above. The wall paper will still follow the same lineillustrated in Figure 1 under these circumstances.

In use of the device, the paper unrolling from roll R passes between theguide roller 78 and the applicator roller means 64, 66, 68. The paperrotates these rollers, so that a uniform coating of paste is applied tothe paper. The paper then passes about roller 78, and between the spacedguide bars 36, 38, as shown in Figure 1. Then, the paper passes aboutthe roller 24, which is pressed against the wall, not shown, so that thepaper will be properly hung upon the wall.

In the event that the paper is being hung in a space too small toaccommodate the roller 24, a brush having bristles of a length toapproximately two inches is mounted adjacent the roller 24. Said brushis illustrated in Figure 6, and comprises an elongated, wide, flatsupport bar 82 the opposite ends of which are formed with depending arms84 terminating at their lower ends in outwardly projecting, rectangularlugs86 engaging in slots 27 of arms 22. Bristles 88 project forwardlyfrom and are embedded in bar 82.

While the paper is traveling from one to the opposite end of the frame,the selvage may be trimmed therefrom by proper placement of blade orblades 44.

Further, when the ends of the applied paper must be cut, the endtrimming blade 32 is employed in the manner previously described herein.

The purpose of blades 44, primarily, is to trim the selvage. However,these blades have the secondary purpose of pretrimming a strip of paperto fit the same into a relatively small space such as one existingbetween two window frames.

It may be further noted that one of the discs 50, 52, or both of them,may be calibrated or otherwise marked on its face to indicate when apredetermined amount of paper is left upon the roll.

It is believed apparent that the invention is not necessarily confinedto the specific use or uses thereof described above, since it may beutilized for any purpose to which it may be suited. Nor is the inventionto be necessarily limited to the specific construction illustrated anddescribed, since such construction is only intended to be illustrativeof the principles it being considered that the invention comprehends anyminor change in construction that may be permitted within the scope ofthe appended claims.
